Can anyone tell me where I got this? I just don't remember. I don't think I bought it - I think I may have either received it in a mail or maybe as a season reward?
It's a greater unbreakable heart rune with no 4th stat. I'm not bothered that much by it, but it seems counterintuitive to have runes named with an ability that don't actually have that ability. It might also confuse newer players.
